cosmoavs/statesync

• A cosmos-sdk module which helps to retrive L1 on-chain state in the context of cosmos app.
• It facilites querying of operator set with stake for given block and quorum to be used for consensus and block advancement in cosmos chain.
• Implementation uses OperatorStateRetriever contract via eigensdk

This repository setup can also be used as template to boostrap other modules that require interacting with eigenlayer L1 contracts

Future Improvements

• Add more methods to module to allow querying more complex logic
• Add simulation and more test cases
• Add support for ingesting event logs and checkpoint operator set in KVStore
• Integrate with other standard cosmos modules such as x/epoch and x/evidence
• Create modules which writes updates to cometbft's EndBlock validator set by integrating x/staking and x/slashing standard modules with AVS events
• Add support for BLS signature verification for CometBFT node

Client

service Query {
  rpc OperatorState(QueryOperatorStateRequest)
      returns (QueryOperatorStateResponse) {
    option (cosmos.query.v1.module_query_safe) = true;
    option (google.api.http).get = "/cosmoavs/statesync/{block}/{quorum}";
  }
}

Supports default cosmos chain GRPC, REST and native method calling via keeper
